FIELD OF THE INVENTION

The present invention relates to the field of office furniture, inparticular to occupational disease prevention in an office, and isspecifically a smart office chair with a ventilation function.

BACKGROUND

Office workers spend at least 8 hours sitting in an office chair everyday. For most people, the number of times and accumulated duration ofleaving the office chair during the 8 hours are little. Most of theexisting office chairs have an integrally disposed cushion, which issoft and of a certain thickness. Therefore, if a person spends a longtime of the day sitting in the office chair, the part where the buttocksand the cushion are in contact will be poorly ventilated, which can be abreeding ground for germs and lead to serious health threats.

For example, during summer, although air conditioners are usually turnedon indoors, men or people who sweat a lot are still prone to sweating.Due to the non-breathable cushion and sweating, the buttocks and crotcharea are moist and poorly ventilated, which can easily breed germs. Forexample, for female employees during their menstrual period, the poorventilation in the buttocks and crotch area is more likely to enhancebacterial growth and affect their health, and women have weaker physicalconditions during their menstrual period.

In the prior art, in order to achieve a ventilation function, manycompanies in the home furnishing or furniture industry, such as IKEA,have proposed a variety of office chairs with a ventilation function.The most common office chair with the ventilation function is typicallymade of plastic material. These chairs have a seat back, a chair leg anda seat. The seat is provided with a plurality of through-holes, so thatwhen a person sits on the chair, the ventilation is relatively adequate.However, such chairs will be cold in winter and when the temperature islow, and thus less suitable for women in their menstrual period andpeople who cannot handle the cold.

For example, a patent titled “smart electric heating office chair”(patent number: CN201610819063.9; publication number: CN106388371A) alsodiscloses an office chair with a smart heating function, the mainpurpose of which is to make users comfortable with smart heating. Ittargets the user's shoulders and neck, but does not involve theimportant ventilation function for the buttocks.

In summary, the existing office chairs designed with a ventilationfunction are mostly made of plastic or other materials, which are toohard for long-term use. Moreover, they are cold in winter, and thus notsuitable for women in special periods such as menstrual period, or userswhose buttocks cannot handle contact with cold objects. Other officechairs do not seem to have a ventilation function, especially aventilation function for the buttocks, which means that the existingoffice chairs do not have a smart ventilation function.

DETAILED DESCRIPTION

The invention will now be described in further detail with reference tothe drawings. The drawings are simplified schematic diagrams. The basicstructure of the invention is illustrated merely in a schematic manner.Therefore, only the configurations related to the present invention areshown. The invention discloses a smart office chair with a ventilationfunction.

First Embodiment

FIG. 1 to FIG. 3 show a smart office chair with a ventilation function,which comprises a seat back 1, a seat 2 and a chair leg 3. The seat back1 is fixedly connected to the seat 2. The seat 2 is provided with achair leg 3 at the bottom. The seat 2 comprises a seat frame 21 and asecond elastic article 22 wrapping around the seat frame 21. The secondelastic article 22 of an upper surface of a middle portion of the seat 2is provided with six first vent holes 221. The first vent hole 221 isprovided therein with a third elastic article 222. The reason fordisposing the first vent hole 221 on the second elastic article 22 ofthe upper surface of the middle portion of the seat 2 is that thisposition is typically where the human buttocks are in contact with theoffice chair. Disposing the first vent hole 221 at this position canachieve the ventilation function most effectively.

In this embodiment, the third elastic article 222 is disposed in thefirst vent hole 221 in an arrangement such that the third elasticarticle 222 is embedded within the first vent hole 221, the outersurface thereof in close contact with the inner surface of the firstvent hole 221. The third elastic article 222 will fall or slide outwardfrom the first vent hole 221 only when an external force is applied.

The seat frame 21 forms a receiving space. The receiving space comprisestherein a circular plate 23. The circular plate 23 is provided thereonwith a first groove 231. The position of the first groove 231corresponds the position of the first vent hole 221. The first groovedefines therein a vertical connector 232. The other end of the verticalconnector 232 is fixedly connected to the third elastic article 222.

The seat frame 21 may have different designs according to the shape ofthe office chair, but in general, the seat frame 21 is rectangular.However, the seat frame 21 is merely some brackets fixedly connectedtogether. If iron brackets are used as the seat frame 21, these bracketsmay be fixedly connected by welding, or through-holes may be provided onthe bracket so that the brackets are fixedly connected together by boltsand nuts or by screws.

The numbers and positions of the first groove 231, the first vent hole221, and the vertical connector 232 are corresponding, and therefore aresix, such that the vertical connectors 232 can be connected to thecircular plate 23 through the first groove 231, and can also beconnected to the third elastic article 222. Specifically, the first venthole 221 has a T-shaped cross section in the vertical direction and thethird elastic article also has a T-shape. As such, the third elasticarticle 222 can be better embedded into the first vent hole 221 and willnot protrude above the first vent hole 221, making users feel a foreignbody sensation due to the protrusion. However, it is not limited to aT-shape, and may be of other shapes. The main purpose thereof is toprevent the third elastic article 222 from protruding out of the outersurface of the second elastic article 22, making the user uncomfortable.

The material of the third elastic article 222 may be the same as that ofthe second elastic article 22. The second elastic article 22 may be theelastic article of the office chair surface commonly found in themarket. The details are not described herein. Of course, the thirdelastic article 222 may also be made of other materials, such asdirectly made from latex or rubber. More preferably, the outer jacket ofthe third elastic article 222 is provided with an elastic latex orsilica gel, and is provided with an elastic protrusion. As such, thethird elastic article 222 can be better embedded into the first venthole 221. The end of the vertical connector 232 connected the circularplate 23 is provided with external threads. The first groove 231 isprovided therein with internal threads matching the external threads.The vertical connector 232 and the first groove 231 are connectedtogether by matching the internal threads and the external threads. Assuch, in case of failure of the office chair, especially when thevertical connector 232 is worn or damaged, the vertical connector 232can be removed for maintenance, which is more convenient. The verticalconnector 232 and the first groove 231 may be connected in othermanners. For example, the vertical connector 232 may be T-shaped. Thehead end of the T shape is used for connection to the first groove 231.The first groove 231 is provided therein with at least two secondconnecting holes. The vertical connector 232 is fixed in the firstgroove 231 with screws. The number of the second connection holes is notlimited, and is preferably two. More preferably, the other end of thevertical connector 232 has an arrow-shape, inserting into the middle ofthe third elastic article 222. The “arrow shape” means that the otherend of the vertical connector 232 extends a connecting portion along asouthwest direction and a southeast direction 45° respectively from itsapex. The shape of this end is like an arrow. Inserting into the middlethe third elastic article 222 in such manner can better connect thevertical connector 232 and the third elastic article 222 together. Thevertical connector 232 is not easily detached from the third elasticarticle 222. The circular plate 23 is provided with a first connectionhole at the center, connected to a first motor 24 through the firstconnection hole such that the circular plate 23 can move about an axisof the first motor. The first motor 24 is fixed on the seat frame 21.The first motor 24 may be a micro-motor, such as a planetary gear motor.The connection of the first connection hole 24 and the circular plate 23through the first connection hole may be that an axis of the first motor24 is connected to a connecting flange, and then the connecting flangeis connected to the circular plate 23 by screws passing through thefirst connection hole. The connection manner may be different, dependingon the connecting flange. Moreover, since the circular plate 23 isconnected to the third elastic article 222 through the verticalconnector 232, and the third elastic article 222 is in turn fixed in thefirst vent hole 221, the position of the circular plate 23 in thehorizontal direction is defined. When the first motor 24 is operating,the rotation of its motor shaft will drive the circular plate 23 to movein the vertical direction along the motor shaft of the first motor 24.

A side of the circular plate 23 is provided with a second groove 233.The second groove 233 is provided therein with a wire rope 234. The wirerope 234 is a loop rope, which also loops around a side of a firstpulley 25. The first pulley 25 is fixedly connected to the second motor26. In other words, the operation of the second motor 26 will drive thefirst pulley 25 to rotate. The rotation of the first pulley 25 willdrive the wire rope 234 to move. The movement of the wire rope 234 willdrive the circular plate 23 to rotate. Since the third elastic article222 connected to the circular plate 23 has come out of the first venthole 221 at this time, the rotational movement of the circular plate 23is no longer defined.

The office chair further comprises a power module 27. The power module27 is connected to a controller 28, a temperature sensor 29, a humiditysensor 30, a fan 31 and a heating sheet 32 respectively. The temperaturesensor 29 and the humidity sensor 30 are disposed in a side of thesecond elastic article 22 in contact with the human body. The fan 31 andthe heating sheet 32 are disposed at an edge of the seat frame 21. Thetemperature sensor 29 and the humidity sensor 30 are disposed in thesecond elastic article 22 of an upper surface of the seat 2. As such,the temperature and humidity of user who is sitting can be bettersensed. The information is then fed back to the controller, and thecontroller issues a corresponding command.

The smart office chair further comprises an indexing plate 33. Theindexing plate 33 is connected to the second motor 26. The purpose ofsuch arrangement is to make it convenient for the controller 28 tocontrol the rotation angle of the circular plate 23, facilitating backrotation after the rotation.

Second Embodiment

The difference from the smart office chair in the first embodiment isthat the number of the first vent hole 221 is one, the number of thethird elastic article 222 is also one, the number of the first groove231 is also one, and the number of vertical connector is also one.

In order to better achieve the ventilation function, the size of the onefirst vent hole 221 may be slightly larger, such as 5 cm in diameter.

In other words, the number of the first vent hole 221 is at least one,which may be six as described in the first embodiment, and may be three,five or ten. However, it should be considered comprehensively accordingto factors such as the area of the seat 2.

The advantages of the office chair of the first embodiment and thesecond embodiment are:

Compared with the prior art, the technical solution of the presentinvention has the following advantages:

According to their own situation, users can preset a temperature valueand a humidity value regarding the temperature and humidity of thebuttocks and the office chair which may make them uncomfortable.

After the user has sat on the office chair for some time, when thehumidity sensor 30 and the temperature sensor 29 sense that the localtemperature and humidity of the seat of the office chair used by theuser exceed a preset value, the controller 28 will control the firstmotor 24 to operate, wherein the first motor 24 drives the circularplate 23 to move downward in the vertical direction, i.e. the directionin which the third elastic article comes out of the first vent hole 221,such that the vertical connector 232 brings the third elastic article222 away from the first vent hole 221. At the same time, the controller28 will control the second motor 26 to operate, wherein the second motor26 drives the first pulley 25 to rotate, driving the circular plate 23to rotate, such that a larger space is left near the first vent hole221. At this time, the controller 28 will control the fan to operate.The inside and outside of the office chair form a good ventilationchannel, taking away the temperature and humidity on the surface of theseat, especially the middle portion of the seat where the buttocks arelocated, keeping the buttocks ventilated and dry.

In winter, in an air-conditioned room in summer, or when women want theseat not to be cold, when the humidity sensor 30 and the temperaturesensor 29 sense that the local temperature and humidity of the seat ofthe office chair used by the user exceed a preset value, the controller28 will control the second motor 26 to operate, wherein the second motor26 drives the first pulley 25 to rotate, driving the circular plate 23to rotate, such that when the position of the third elastic article 222corresponds to the first vent hole 221, the controller 28 will controlthe first motor 24 to operate. The first motor 24 will drive thecircular plate 23 to move upward in the vertical direction, such thatthe vertical connector 232 inserts the third elastic article 222 intothe first vent hole 221. At this time, the controller 28 controls theheating sheet 32 to heat up, warming up the chair. When the temperaturesensor 29 senses that the preset temperature value is reached, theheating sheet 32 is turned off. At this time, the office chair isalready warmed up.

Third Embodiment

Referring to FIG. 4, what is different from the first embodiment and thesecond embodiment is that the smart office chair of the presentembodiment further comprises a second circular plate 34. The secondcircular plate 34 is provided with a third connection hole at thecenter, connected to the second motor 26 through the third connectionhole. The second circular plate 34 is provided with a third groove 341.The third groove 341 is provided therein with a second verticalconnector 342. The second vertical connector 342 is connected to thefourth elastic article 35. The fourth elastic article 35 is defined in asecond vent hole. The second vent hole is disposed on a lower surface ofthe seat 2. A side of the second circular plate 34 is provided with afourth groove 343. The fourth groove 343 is provided therein with asecond wire rope 36. The other end of the second wire rope 36 loopsaround a second pulley 37. The second pulley 37 is fixedly connected tothe first motor 24. The second motor 26 is connected to the controller28.

The size of the second circular plate 34 may be the same as or differentfrom that of the circular plate 23.

The size of the third groove 341 may be the same as or different fromthe size of the first groove 231. The numbers may be the same ordifferent. The number of the first grooves 231 mainly depends on thenumber of the first vent hole 221. The number of the third groove 341mainly depends on the number of the second vent hole.

The shape of the second vertical connector 342 may be the same as theshape of the first vertical connector 232, or may be arrangeddifferently. Moreover, the shapes of different vertical connectorslocated on the same circular plate may be the same or different. Ofcourse, for the convenience of processing and cost considerations, theshapes of vertical connectors 232 located on the same circular plate 23are preferably the same and standardized. Preferably, the sizes andshapes of the same component are the same.

Similarly, the second motor 26 may be a micro-motor, such as a planetarygear motor, and may be the same as or different from the first motor 24.In addition, the second motor 26 may also be connected to a secondindexing plate.

Compared with the prior art, the technical solution of the thirdembodiment has the following advantages:

The rotation of the first motor 24 can bring the third elastic article222 away from the first vent hole 221 as described in the firstembodiment and the second embodiment, and can also drive the secondpulley 37. However, at this time, the second pulley 37 does not rotate.In the present invention, the rotation angle of the circular plate 23 isnot too large. It is only intended to space apart the third elasticarticle 222 and the first vent hole 221, and the fourth elastic article35 and the second vent hole to form a ventilation passage in thereceiving space. Therefore, when the second motor 26 rotates and drivesthe circular plate 23 to rotate by a certain angle, the fourth elasticarticle 35 is detached from the second vent hole and rotates at themoment of detachment. As such, vent holes are provided in the upper andlower directions of the seat, enhancing ventilation.

In the description of the present invention, it should be understoodthat the terms “one end”, “end”, “length”, “the other end”, “both ends”,“vertical”, “upper”, “lower”, etc. are indicated based on theorientation or positional relationship shown in the drawings, which ismerely for the convenience of the describing the invention andsimplifying the description. It is not intended to indicate or implythat the device or component referred should have a particularorientation and is constructed and operated in a specific orientation.Therefore, it cannot be construed as limiting the invention.

In the present invention, unless otherwise explicitly stated anddefined, the terms “dispose”, “wrap”, “connect” and the like should beunderstood broadly, and may be, for example, a fixed connection, adetachable connection, or an integral connection. It may be a mechanicalconnection or an electrical connection. It may be direct connection orindirect connection through an intermediate medium, and may be aninternal communication of two components or an interaction relationshipof two components, unless explicitly defined otherwise. The specificmeanings of the above terms in the present invention can be understoodby those skilled in the art according to specific situation.

Although the present invention has been disclosed above, the presentinvention is not limited thereto. Any changes and modifications may bemade by those skilled in the art without departing from the spirit andscope of the invention.
